Unitron U-11 Polarizing Rotary Microscope Stage and Head Assembly. This is the top half of microscope as shown. The base is NOT included. Both lamphouses work. Sold for parts/repair only. Will need a good cleaning, alignment, etc. I did notice the flip-out for the condenser does not flip out easily. The stage rotates smoothly as do other adjustments/controls. However this has been sitting for several years so a good cleaning, aligning and repair is imperative. For safe and proper shipping this will be partially disassembled so assembly will be required.
